Most Heavily Partisan Industries

Election Cycle

The most partisan industries are determined by calculating the amount of money given to Democratic or Republican candidates and
party committees compared to all the money given, including money going to outside spending groups and other PACs. The pie charts
show the Democrat/Republican split; money not categorized as being connected to either party is not included in the charts.

The list below shows the industries and interest groups that gave the highest proportion of their dollars to one party or the other.
